Pursuant to my 3/16" x 1/2" aluminum bar quest, I'm thinking of getting some bids for some 12" long bars -- assuming that a shop will just whack them out of 3/16" plate.
I know how to call out "mill finish" -- is there a good way to call out "about as good as mill finish but no worse", assuming I'm working with a machine shop that wants everything specified down to a gnat's eyelash?
I mean -- I want something better than +/- 1/16" tolerances and visible saw marks, because I can do that with my own hack saw. But I don't want to pay for anything better than +/- .010 and kinda-sorta-good finish, either.
